squirrelmail的imap问题

zjzhouzg

我在debian sarge 3.1上安装了exim＋squirrelmail＋courier-imap。都成功安装，exim收发信件都正常，squirrelmail的测试页也通过，测试如下
This script will try to check some aspects of your SquirrelMail
configuration and point you to errors whereever it can find them. You
need to go run conf.pl in the config/ directory first before you run
this script.    Checking outgoing mail service....
   SMTP server OK (220 mail.cn ESMTP Exim 4.50 Fri, 23 Dec 2005 10:59:30 +0800)

Congratulations, your SquirrelMail setup looks fine to me!


但是登陆后时候提示"ERROR : Connection dropped by imap-server."
imap已经开启，143端口也没封，不知道为什么squirrelmail链接不上imap，请高手帮忙，这个问题我找了好长时间都没解决！
